Step-by-step explanation:
r = 7(t+3)
expanding the bracket
r = 7t + 21
bringing t to the left hand side
7t = r - 21
divide both sides by seven
t= <u>r-21</u>

Answer: Decreasing
Step-by-step explanation:
Given : The per capita birth rate of a species of duck is 0.12. The per capita death rate of that same duck species is 0.14. Assume immigration rate equals
We assume that the immigration rate equals emigration rate.
Since the per capita death rate of a species of duck is greater than the per capita birth rate (0.14>0.12) that means the population of ducks are deceasing.
